The San Jose woman who is accused of killing an elderly woman Sunday morning while driving under the influence had a blood alcohol content of at least 0.15 percent, according to the Santa Clara County District Attorney’s Office.

Leticia Daisy Martinez, 28, is facing five felony and two misdemeanor charges in connection with the hit-and-run death of 79-year-old Diana Pundsack, who was gardening when she was struck by a Chevy Suburban that came crashing across her front yard.

Martinez could be sentenced to more than 12 years in prison if convicted on all charges, which include gross vehicular manslaughter and hit and run resulting in death, according to the District Attorney’s Office. Martinez is scheduled to make her first court appearance Thursday.

Pundsack was gardening at her home near Calero and Snell avenues in South San Jose when a 1999 Chevy Suburban jumped the curb and plowed across the front yard. The vehicle slammed into Pundsack and the house, crushing the front corner of the structure and a wall of the front room.

Pundsack was pronounced dead after she was rushed to Santa Clara Valley Medical Center.

The crash was the second of three that Martinez was involved in within minutes, police say.

The first occurred about 9:30 a.m., when the Suburban struck a Honda sedan near Blossom Hill Road and Entrada Cedros, just off Highway 85. The damage was minor, but police say Martinez left the scene. Police say the 26-year-old man who was driving the Honda followed the fleeing SUV.

With the Honda close behind, the woman driving the Suburban turned south on Snell Avenue and then attempted to make a sudden left turn onto Roading Drive. The Suburban jumped the curb and a low stone wall in front of Pundsack’s corner house.

Police say Martinez backed up and sped away. The SUV made several turns before striking a parked car on Bridle Way, off Calero. Police say the owner of that car, another Honda, had been washing and polishing his vehicle and had fortunately stepped away just seconds before the Suburban slammed into it.

Martinez and three passengers abandoned the SUV, according to police, and may have tried to flee on foot, but officers arrived and stopped them. Some neighbors said that bystanders arrived first, after following the Suburban from Pundsack’s house, and helped block the driver and passengers.

Martinez also was charged with hit-and-run driving causing property damage, stemming from her final crash into a parked vehicle on Bridle Way. She has also been charged with driving without a license.
